I hope he never faces that situation but if the case should arise I hope there is someone there to step in. Just as I hope that if someone were to attempt to grab my wife or one of our daughters out of a parking lot there would be someone willing to step to the plate.
Edited to add I hope I never have to draw my carry weapon again even for something as minor as I had last night. But if I ever saw someone in real need of help I am willing to give all I have.
